Researchers from School of Chemistry Report Findings in Phenothiazines

March 4, 2014



By a News Reporter-Staff News Editor at Life Science Weekly -- New research on Phenothiazines is the subject of a report. According to news reporting out of Himachal Prades, India, by NewsRx editors, research stated, "Guar gum-cerium (IV) tungstate nanocomposite (GG/CTNC) cationic exchanger was synthesized using simple sol gel method. The GG/CTNC was characterized using X-ray diffraction (XRD), Fourier transmission infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and energy dispersive X-ray spectrophotometer (EDX)."

Our news journalists obtained a quote from the research from the School of Chemistry, "The XRD studies confirmed amorphous and fibrous in nature of GG/CTNC. The high percentage of oxygen in the nanocomposite material confirmed the functionality tungstate (WO4-). The ion exchange capacity of GG/CTNC for Na-* ion was observed to be 1.30 mequiv g(-1). The hybrid exchanger was used as potential adsorbent for the removal of methylene blue (MB) from aqueous system. The correlation coefficients value indicated a good fit of monolayer Langmuir model to the adsorption of methylene blue onto GG/CTNC. The adsorption kinetic study revealed that the adsorption process followed the pseudo second order kinetic."

According to the news editors, the research concluded: "The Gibbs free energy (Delta G) values confirmed the spontaneous nature of adsorption process."
